Title: Permanent magnet embedded rotor
Inventor: OKUMA SHIGERU
IPC: H02K1/27
Filed: 1999-10-21
Abstract: PROBLEM TO BE SOLVED: To provide a permanent magnet embedded rotor having improved motor performance by reducing a gap in an accommodation hole, when a permanent magnet is embedded into the accommodation hole. SOLUTION: A section that is vertical in the axial direction and an accommodation hole 3 formed into a trapezoid shape where a projection side faces a central side are provided in a rotor core 1. Permanent magnets 5a and 5b, where a section that is vertical in an axial direction is formed into a trapezoid, are used for a permanent magnet 5. The permanent magnets 5a and 5b are inserted into a central part 3a and an outer-periphery part 3b of the accommodation hole 3, thus reducing the gap between the permanent magnets 5a and 5b in the accommodation hole 3 and that between the permanent magnet 5b and the end part of the accommodation hole 3.  Also, since dispersion in the thickness of the permanent magnets 5a and 5b is small, the difference between the width dimension of the accommodation hole 3 and the thickness dimension of the permanent magnets 5a and 5b can be reduced, thus decreasing the gap between the accommodation hole 3 and the permanent magnets 5a and 5b.

Title: Obstacle detector
Inventor: NISHIMOTO YUKIO
IPC: G01S15/08
Filed: 1993-11-30
Abstract: PURPOSE:To change alarm contents according to a change in a running state of a vehicle and improve its running safety by altering an alarm table, whose alarm contents are classified according to the distance from the vehicle to the obstacle, on the basis of the running state of the vehicle. CONSTITUTION:A microcomputer 40 outputs alarm contents on the basis of the distance L to a detected obstacle, but has the alarm table whose alarm contents are classified according to the distance from the vehicle 1 to the obstacle, so alarm contents are outputted according to the contents of the alarm table. If, however, one of detectors 34-36 of a driving state detector 33 or a travel environment detector 37 detects the vehicle being in a dark state, the degree of danger is different before and after a change in driving state, etc., even if the distance L from the vehicle 1 to the obstacle is the same, so the microcomputer 40 alters the contents of the alarm table so as to hold the safety of the travel.

Title: Instrument for measuring radiation
Inventor: YANO KENICHI
IPC: G01T1/167
Filed: 1999-10-21
Abstract: PROBLEM TO BE SOLVED: To reduce an influence of an α-ray nuclide such as radon and thron contained in the air to enhance measuring precision, in gas monitoring for taking an outside air into an ionization chamber to detect β-rays. SOLUTION: An ionization current output from the ionization chamber 10 is converted into a voltage signal by an electrometer 20. The voltage signal is branched into two paths to be differentiated in the path A by a differentiating circuit 30. A pulse-height discriminator 32 takes out only large pulses corresponding to α-rays out of a differentiated result differentiated hereinbefore and a counting circuit 34 counts the pulses of the α-rays to find a counting rate. The voltage signal is integrated with a prescribed integral time constant in the path B by an integrating circuit 40 to be averaged. A found average voltage is measured by a voltmeter 42 to be digitized.  A computing part 50 converts the α-ray counting rate found in the path A into a value of the average voltage to be subtracted from the average voltage found in the path B, and the influence of the α-ray nuclide is removed thereby from a measured result.

Abstract: PURPOSE: To provide an effective device storing data in an array constituted of a semiconductor ferroelectric memory device and reading data. CONSTITUTION: The ferroelectric random access memory device 200 has plural strings constituted of ferroelectric memory cells 202. The memory cells of the respective strings are connected to individual bit lines 212. The respective memory cells are selectively connected to the bit lines by an access control transistor. For reading data in the memory cells, output voltage stored twice and generated is individually sampled. First reading is destructive and second reading is executed in a state where the cells are in a '0' state. The two sampled outputs are compared. When the amount of first reading exceeds that of second reading by the amount of a threshold, '1' is outputted. When not, '0' is outputted. When the cell stores a '0' bit, first reading generates power smaller than a case when first reading is not delayed and recognizes the detection of the storage of a '0' bit value.
